چکیده انگلیسی
In this work, solventless grafting of NVP on to LDPE surface was conducted by high-energy electron beam radiation (10Â MeV) at dose range 10-200Â kGy in absence of solvent. As NVP could not wet LDPE surface, polyvinylpyrrolidone (PVP) (with various k-values and thus various weight percentages) was solved in NVP and then this tacky polymer was used for coating and grafting purposes. The FT-IR spectra showed that the concentration of characteristic bands of the NVP -grafted LDPE increased with increasing radiation dose as well as the percentage of grafting significantly increased up to 32%. Furthermore, hydrophilicity, yield of gel content and topology of NVP-grafted LDPE films and sheets were studied.
